洪堡 water baths feature a microprocessor-based digital controller for precise temperature control throughout their temperature range of ambient to 180°F (82°C) at an accuracy of +/-0.输入跨度的1%. The dual digital display simultaneously shows the set point 和 the process temperature at a glance.
洪堡 water baths are fully insulated to help maintain constant temperatures easily. Models H-1390 和 H-1392 can accommodate (12) 4" diameter or (3) 6" diameter Marshall specimens at a time. And the model H-1394 can accommodate (16) 4" 和 (9) 6" diameter Marshall specimens at a time. All models include 一种不锈钢架子制造技术, which supports specimens while allowing 2" of free circulating water above 和 below specimens. Models H-1390 和 H-1394 also utilize a magnetic stirring bar to induce water flow within the bath 和 ensure a uniform temperature is maintained. Model H-1392 does not have a magnetic stirring bar. All exposed areas are stainless steel 和 the front control panel is both water 和 corrosion resistant.
Microprocessor-based control for precise temperatures throughout the range. Includes magnetic circulator, ensuring constant water temperature, 和, 一种不锈钢架子制造技术, which st和s 2" (51mm) above the bottom of the unit for free circulation of water above 和 below test samples. 音量为7.76加仑(29加仑).40L) 和 dimensions are: ID: 19.5" W x 11.5“深× 8”高(495.3 x 292.1 x 203.2mm).
